It seems like when I disengage my E-brake in the mornings when I go to work I sometimes get a "pop" from the back. It's a rather noticeable thud and my girlfriend noticed it yesterday. I only hear this when I have used the E-brake and then only sometimes, maybe once every week or so. As a test I have parked my car without the E-brake engaged and I have never had this thud/pop.

I can't help but think that somehow the E-brake is sticking somehow. Any input on this? Btw, I'm running Stoptech ST-40 and ST-45 and KW V2 coils.

Thanks in advance.

 

Wet freezing weather? Car out all night? Yes the emergency brake will freeze ON. Do not use in these conditions.

 

Thanks for commenting. I park the car in an underground parking garage in my apartment building so it's not outside but it does appear to happen when it has been raining. I suspect it is from the light coating of rust that usually forms on the rotors after driving in the rain. Would you agree?

 

Agree.

 

Yep. Sounds like it's just slight oxidation. Shouldn't be a big concern.
